In a recent lecture debating the increase of CO2 volume caused by a high number of humans being alive and breathing, this is what Bill Gates had to say:

"The world today has 6.8 billion people... now if we do a really great job on new vaccines, healthcare, reproductive health services, we could lower that (number) by perhaps 10 or 15%." "Vaccines are something I love."

Now, please correlate this information with the last year's 'shocking' report stating that Bill Gates and Warren Buffet convinced 30 billionaires to donate half their wealth to 'Bill and Melinda Gates Foundation' that is currently (among others) developing new vaccines.
